The EMU3000 series was purchased as part of the then
Taiwan Railways Administration's (TRA) plan to replace its aging fleet by 2024. That plan called for the purchase of 600 intercity cars, 520 commuter cars (
EMU900 series), 102 locomotives, and 60 un-electrified passenger cars. Additionally, the EMU3000 series was expected to increase TRA's service capacity in
Eastern Taiwan, where demand for tickets is high and often sell out around major holidays. Bidding for the intercity trains commenced in October 2018 and saw entries from two companies,
Hitachi and
Stadler. The TRA announced that Hitachi won the bid in December, and a contract was signed in January 2019 for . The train's design was revealed to the public in November 2020. The EMU3000 series are assembled in Hitachi's Kasado Plant in
Kudamatsu,
Yamaguchi Prefecture. While the first group of trains were slated to arrive in June 2021, the COVID-19 pandemic pushed back the trains' delivery. The first train was unloaded in the
Port of Hualien on 31 July 2021. The remaining trains are scheduled to arrive by 2024. == Features ==
